Title: Spray booth with energy saving and fire protection systems
Inventor: NAPADOW STANLEY C
IPC: B05B15/12
Filed: 1979-12-28
Granted: 1982-10-26
Abstract: ABSTRACT This invention teaches an improved exhaust system to be used with a paint spray booth and having a contin-uously operating power exhaust fan. The exhaust system has a damper that is opened when spraying actively is tak-ing place in the spray booth and that is closed when there is no spraying actively taking place in the spray booth. A control switch is mounted in any of several locations to determine when the spray gun is in use or is not in use. Thus, the control switch is actuated when the spray gun in hung up ... indicating a nonuse condition of the spray system; whereupon use of the spray gun lifts the gun from the hook to indicate spraying activity. A motor drives the damper to the opened position; and a spring biases the damper to the closed position. A timer is also used to delay the closing of the damper until between twenty and pos-sibly two hundred seconds have lapsed after spraying acti-vity has terminated. This purges the spray booth while yet allows for automatic damper control under normal spray-ing sequences of use and nonuse. A fire sensing switch is used to deenergize the damper motor to allow the damper to be closed in the event of a fire.

Abstract: Abstract An asymmetric cylinder electron capture detector comprises a cylindrical electrode configured to define an ionization volume, a source of ionizing radiation disposed within the ionization volume, a cylindrical collector electrode, the respective cylindrical electrodes being in coaxial alignment but having their ends spaced apart, means for directing a gas past the collector electrode into the ionization volume, and means for applying a difference of electrical potential between the electrodes. The two electrodes are mechanically connected via an inter-mediately disposed cylindricaly insulator cylinder.  The collector electrode is received in one end of the insulator cylinder, and the electrode defining the ionization volume is received within the other end of the insulator cylinder. The collector electrode has an elongate portion extending into the interior of the insulator cylinder, but spaced apart from the inner surface of the insulator cylinder. The elongate portion of the collector electrode may extend into the insulator cylinder up to a position coplanar with the end of the electrode defining the ionization volume. The insulator cylinder provides a flow path from the collector electrode to the ionization volume and permits turbulence to be introduced into gas flow by means of a transverse gas exit port.

Abstract: ABSTRACT OF THE DISCLOSURE       Occasionally, large-scale electric motors are provided with an oil-cooling device for the sheet-metal container. In this case, the sheet metal container is cooled directly by means of bores and cooling oil flowing through them, or else, special cooling coils are provided, the cooling coils passing axially through the sheet-metal container. For the latter embodiment, the cooling effect is lessened by the transitional losses. In the first embodiment, considerable oil leakage must be taken into consideration, the oil running into the lowermost portion of the housing, and possibly endangering the passing generator drain. The invention provides measures for the prevention of the destruction of the insulation of the drain. These measures essentially consist in designing the flange which accepts the drains as an upwardly narrowing funnel-shaped design having bores, and above this flange a pot-shaped element is provided, which has bores in its bottom, which bores are congruent with the bores of the flange. The lateral walls of the pot-shaped element extend higher than the coil interconnections entering into the drains in the area of the pot-shaped element, and each of the bores is sealed by a sealing flange, whereby the gap between one drain and the sealing flange is sealed by means of a non-harden-ing sealing mass, and the pot-shaped element is completely filled with a casting resin.

Abstract: 48D-274 Canada CENTRIFUGE TUBE HOLDER     Abstract of the Disclosure A centrifuge  tube holder which not only provides support for the tubes in a vertical orienta-tion when placed on a workbench, but also horizontal and radial support when the tubes are placed in a centrifuge rotor.  The tube holder has at least two sections which are pivotally connected to allow for upright or vertical  orientation of the tubes when placed on a workbench.  The two sections can be pivot-ally oriented with respect to each other to place the tubes horizontally in a centrifuge rotor at different radial angles with respect to each other with reference to the spin axis of the rotor.  The holder also incor-porates means for securely holding the tubes within the holder while they are being transported, so that the holder can be inverted without the escape of the tubes.          On the other hand, the biasing or securing means for the tubes in the holder is eliminated when the holder is at rest on the workbench to permit convenient and easy insertion or removal of the centrifuge tubes.  The tube holders act in conjunction with a spacer within the rotor bowl to not only provide the proper placement of the centrifuge tube holders during centrifugation, but also permit extraction of the holders from the rotor bowl  to remove  essentially  all  obstructions within the rotor bowl for easier cleaning after a centrifugation run.

Abstract: ABSTRACT OF THE DISCLOSURE   There is disclosed a method for the preparation of a homogeneous, physically stable colloidal elemental iron dispersion of colloidal iron particles having a size in the range of from about 10 Angstrom units to about 200 Angstrom units.  The method comprises preparing a solution of a passive polymer in an inert solvent, and incrementally adding thereto an iron precursor, at a temperature at which the iron precursor will lose at least one ligand and become bound to the passive polymer and thermally decompose to produce elemental iron particles, the process being carried out in an inert atmosphere.  Such dispersions may be used per se as catalysts, or may be used for the preparation of supported colloidal iron catalysts.  The dispersion may also be used for the preparation of ablative optical recording media, and for the preparation of magnetic xerographic developer materials.
